The absolute maximum Bending Moment in a simply supported beam of span 20 m due to a moving UDL of 4 t/m spanning over 5 m is
Influence line diagram for a truss member is shown in the above figure. Positive values indicate tension. Dead load of the truss is 20 kN/m and the live load is 10 kN/m. Live load is longer than the span. Maximum tensile force in the member is:
The influence line for horizontal thrust of a two- hinged parabolic arch of span i’ and rise 'h' will be shown in
A Warren truss is supported as shown in the given figure. Which one of the following diagrams represents the influence line for the force in member U3U4?
A simply-supported beam with overhangs is shown in the figure. The influence line diagram for shear in respect of a section just to the right of the support 'A wiil be as shown in
A simply supported beam is shown in the figure-I. The influence line for the beam is drawn in figure-II, Which one of the following statements is correctly associated with the figure-II?
Consider the following statements:
1. An influence line for a function (example: moment shear force, reaction, deflection) in a structure is a curve which shows its variation at a particular section of the structure for various positions of a moving unit load.
2. The influence line for bending moment/shear force must not be confused with bending moment diagram and shear force diagram for the structure.
3. The bending moment diagram and shear force diagram shows the moment/shear values at all sections of the structure. The influence line diagram for BM/SF is always drawn for a moving unit point load and for a particular section only
Of these statements:
Which one of the following equations represents influence line of fixed end moment at B of the fixed beam AB of length l with origin at A?
